Solution Overview
Problem
Existing floor care tools are costly, require multiple components, and create storage challenges due to their specificity and frequent replacement needs, especially when used with liquid products, leading to hazards and inefficiencies in cleaning processes.
Innovation Solution
A universal handle system with interchangeable tool heads that includes a locking mechanism and modular design, allowing for various tools such as floor care, painting, and landscaping tools to be connected, reducing the number of pieces needed and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specific floor care tools are used for different cleaning tasks, then cleaning functionality and versatility are improved, but storage space requirements and inventory complexity increase
Solution Approach 1:
The patent implements a universal handle system that can accommodate multiple interchangeable tool heads for different cleaning tasks. The standardized interface allows a single handle to perform sweeping, mopping, polishing, and other floor care functions by simply changing the attached tool head, eliminating the need for multiple dedicated tools and reducing storage space requirements.
Solution Approach 2:
The cleaning system is divided into separate modular components: a universal handle and interchangeable tool heads. Each tool head is designed as an independent module that can be easily attached and detached from the handle, allowing users to select only the needed tool for each specific task, thereby reducing the number of tools that need to be stored simultaneously.
2Productivity
If liquid cleaner is applied to the floor before use, then cleaning effectiveness is improved, but safety hazards and mess increase
Solution Approach 1:
The tool head incorporates an integrated liquid distribution system with reservoirs and applicators that pre-apply cleaner to the floor surface through controlled dispensing mechanisms. This preliminary action is built into the tool itself, allowing cleaner application to occur simultaneously with the cleaning action, eliminating the need for separate pre-application steps that create safety hazards.
Solution Approach 2:
The tool head acts as an intermediary between the cleaner and the floor surface, providing controlled dispensing through built-in reservoirs and application mechanisms. This intermediary system ensures precise metering and targeted application of liquid cleaner, preventing excessive pooling and reducing safety hazards associated with uncontrolled liquid application.
3Reliability
If multiple different tools are required for different cleaning tasks, then task-specific performance is improved, but time consumption for tool switching increases
Solution Approach 1:
The standardized universal interface enables rapid switching between different tool heads while maintaining task-specific performance. Each tool head is designed to fit the universal interface with precise engagement features, allowing quick attachment and detachment without requiring complex alignment or adjustment, thus minimizing tool switching time while preserving specialized cleaning capabilities.
Solution Approach 2:
The tool head interface incorporates dynamic engagement features such as spring-loaded latches or bayonet-style connectors that provide quick, tool-free attachment and detachment. This dynamic design allows users to rapidly switch between different cleaning tools without manual fastening or complex operations, significantly reducing tool switching time while maintaining secure connection during use.
4Quantity of substance
If traditional floor care tools are used, then initial cost is reduced, but durability and longevity decrease
Solution Approach 1:
The system separates the durable universal handle from the consumable tool heads. The handle, being the most expensive and durable component, is designed for long-term use and can be reused indefinitely. Only the tool heads need to be replaced, which are less expensive individual components. This segmentation extends the overall system longevity while maintaining cost-effectiveness.
Solution Approach 2:
The modular design allows the durable handle to be recovered and reused while only the worn tool heads are discarded. This approach maximizes the value extracted from each purchase by separating permanent infrastructure (handle) from consumable components (tool heads), thereby extending the functional life of the system while maintaining affordability.

AI summary
A tool assembly includes an elongated handle and a locking system for attaching a tool head to the handle. The tool head can be a floor care tool or other accessory that can be attached to the handle such that the elongated length of the handle can aid in the use of the tool attached. The locking system includes a keyed locking collar for engaging at least a first portion of the tool head, and a locking cap rotatably positioned on the handle for engaging a second portion of the tool head. The handle can be extendable, such as by telescoping, and can also be overmolded.
